You are angry at the republicans in the US, yet in general, the left wants more government control over our lives.
"My chief can beat up your chief."
(And if you really believe one side wants more control than the other, regardless of side, you've bought it, hook, line and sinker. The question isn't about control, anymore. It's about how to express that control.)
Gay marriage is only an issue because some Republicans feel they have every right to control your personal relationships. A few Republicans also want to ban abortion, which is again a ridiculousness intrusive government control. Let alone tapping every form of communication, tightening immigration restrictions, increasing law enforcement funding etc. Even the idea we can dictate what other country's do inside their brooders suggests a level of control that's unreasonable.
PS: I would love to vote for Ron Paul, but everyone else just seems to pay lip service to the idea of smaller government without intending to do so.
This is completely OT but marriage is by design, its very nature and tradition not a personal relationship. That's why you have a gathering (the wedding itself), someone usually perceived as important presiding, a party (the reception), why you take your vows in public, why its registered in often publicly accessible registry, why you announce it in a newspaper etc, etc. The concept is even established in the common law by which you can, sometimes and in some places, become married by "acting married" in public.
Marriage is for the society much more than it is for the people getting married. And in the western culture governments decided the terms of marriage (also, possibly more importantly, divorce) on and off since antiquity. It's not some new development.
Democrats and Republicans are merely different sides of the same rusty coin.
[edit] For example, in the US the Democrats publicly say they want healthcare to be affordable, in the UK the Conservatives are the right-wing party and publicly say they want to keep healthcare free and available to everyone based on need, not the ability to pay.
